I can confirm that my dealer said the same thing this morning. He wasn't specific about a date other than "next week". Currently there are no prices entered in the system for standalone options but supposedly that will "fill in" next week at the same time. Ditto on the gas guzzler tax.
Looks like BMW is really ramping things up for the US now. In under 24 hours my production slot bumped up from week 8 to week 6 - they've got to nail all this ordering and pricing stuff down ASAP.
